.SH DESCRIPTION
.LP
.B Install
is a utility which simplifies the process of installing a 5.0 system.
.B Install
goes into a built ON workspace (or any kernel source tree),
looks at the Makefiles,
and figures out how to construct the /kernel and /usr/kernel directories.
It then creates a tarfile
.RB "(see " tar "(1))"
containing /kernel, /usr/kernel, and a few related /etc files.  If a
.I target ([user@]machine:/dir)
is specified, the tarfile is either copied to
.IR machine:/dir " (-T) or untarred on " "machine" " in " "/dir" " (-t),"
using the remote user id
.IR user ,
if specified.
With no options,
.B Install
creates a sun4c system from files in the current workspace (as indicated
by $SRC) and places the tarfile in /tmp/Install.username/Install.sun4c.tar.

.SH OPTIONS
.TP 20n
.BI "-w" " ws"
Install the system built in the ON workspace
.I ws.  ws
must be a built ON workspace \(em
.B Install
will not automatically invoke
.BR make (1) .
If \-w is not specified,
.B Install
uses the current
workspace (as indicated by $CODEMGR_WS).  If there is no current workspace,
.B Install
checks to see if you are in an appropriate source directory, e.g. uts/sun4c;
if so,
.B Install
takes files from there.  Otherwise,
.B Install
looks for files under $SRC/uts.
.TP
.BI "-s" " source directory"
where to look for files [default: $SRC/uts].
.TP
.BI "-k" " kernel arch"
the type of kernel to install.  The default is sun4c; however, if you invoke
.B Install
from $SRC/uts/sun4z,
.B Install
assumes you want a sun4z kernel.
.TP
.B "-n"
No target; just create the tarfile in
/tmp/Install.username/Install.sun4c.tar [default].
.BR "-n" " implies " "-p" .
.TP
.BI "-t" " target"
Install the system on
.I target ([user@]machine:/dir).
This means that kernel/unix is copied to
.I machine:/dir/kernel/unix,
etc.
.IR /dir " is typically either " / " or " /mnt.
.BR "-t" " implies " "-c" .
The default remote user id is the same as the local one ($LOGNAME).
.TP
.BI "-T" " target"
Copy the tarfile to
.I target ([user@]machine:/dir).
This creates the file
.I /dir/Install.tar
on
.I machine.
To finish the install, log on to
.I machine
as root, and type
.RB `` "cd /; tar xvf /dir/Install.tar" "''."
.BR "-T" " implies " "-c" .
.TP
.B "-u"
Install unix only.
.TP
.B "-m"
Install modules only.
.TP
.B "-a"
Install unix and all modules [default].
.TP
.B "-v"
Verbose mode.
.TP
.B "-V"
REALLY verbose mode.  Useful mainly for debugging.
.TP
.B "-q"
Quiet mode [default].  Only fatal messages are printed.
.TP
.B "-c"
Clean up.  After a successful install, delete the files created in
/tmp/Install.username.  This is the default behavior if a
.I target
is specified with
.BR "-t" " or " "-T" .
.TP
.B "-p"
Preserve temp files.  This is the default behavior when no
.I target
is specified
.RB ( "-n" ).
.TP
.B "-R"
Recover from a failed
.BR Install .
This is not required, it's just faster than restarting.
A typical scenario is for
.B Install
to run smoothly right up to the very end, but then die with
"Permission denied" when it tries to rsh/rcp to the target machine.
At this point, you log on to the target machine, diddle the permissions,
log off, and type
.RB `` "Install -R" "''."
.B Install
will only have to retry the rsh/rcp,
rather than rebuild the tarfile from scratch.
.TP
.BI "-d" " temp directory"
specifies where
.B Install
should create its temp files [default: /tmp/Install.username].  This is
useful if you have limited space in /tmp (\fBInstall\fR can take as
much as 100MB).
The suffix "Install.username" is always appended.
.TP
.B "-L"
add a system to your library.  This allows you to build a personal
collection of installable systems from various environments and for
various architectures.  When you type
.RB `` "Install -w /ws/ws_name -k arch -L" "'', " Install
creates a tarfile called
.I ws_name.arch.tar
in your library directory (~/LibInstall by default).
.BR "-L" " implies " "-c" .
.TP
.BI "-l" " library file"
Installs the system contained in
.I library file.
You may omit the ``.tar'' suffix.  For example,
.RB `` "Install -l my_ws.sun4c -t machine:/" ''
installs a system you previously built with
.B "-L"
(from sun4c files in my_ws) on
.IR machine:/ .
This is equivalent to typing
.RB `` "rsh machine '(cd /; tar xvf -)' <~/LibInstall/my_ws.sun4c.tar" '',
but it's easier to remember.
.TP
.BI "-D" " lib directory"
specifies the library directory [default: $HOME/LibInstall].
.TP
.BI "-G " glomname
gloms /kernel and /usr/kernel together into a single /kernel directory.
Useful for development work, e.g. use "Install -G good [...]" to create a
"/kernel.good".
.TP
.BR "-o " "{ \fBobj\fP | \fBdebug\fP }"
object directory. The default is "debug".
.TP
.B \-3
32-bit modules only
.TP
.B \-6
64-bit modules only
.TP
.B \-K
Do not include kmdb misc module or dmods
.TP
.B "-h"
Help.  Prints a brief summary of
.BR Install "'s"
options.
.LP
If you are in a directory like $SRC/uts/sun4z when you invoke
.BR Install ,
it will infer that you want to install a sun4z system
from the current workspace.
.LP
If you supply a list of modules, it overrides any of the
.B "-uma"
options.  You only need to specify the basename of the
module(s), e.g. ``\fBInstall ufs nfs le\fR''.
``\fBInstall unix\fR'' is equivalent to ``\fBInstall -u\fR'', and
``\fBInstall modules\fR'' is equivalent to ``\fBInstall -m\fR''.
.LP
You can customize
.B Install
by creating a .Installrc file in your home directory.  .Installrc
should consist of a list of command-line-style options, e.g:
.LP
.nf
.B
	-w /ws/foo
.fi
.br
.nf
.B
	-t labmachine:/mnt -pv
.fi
.LP
.B Install
processes default options first, then .Installrc
options, then command-line options.  In the case of
conflicting options (e.g. \fB-uma\fR), the last one wins.
.LP
In order to use the most convenient form of
.BR Install " (``" "Install -t machine:/" "''),"
you will need to do the following on the target machine:
.LP
.nf
	(1) add your machine name to the /etc/hosts.equiv file
.fi
.br
.nf
	(2) add your username to the /etc/{passwd,shadow} files
.fi
.br
.nf
	(3) chown -R yourself /kernel /usr/kernel
.fi
.br
.nf
	(4) chmod -R u+w /kernel /usr/kernel
.fi
.SH "ENVIRONMENT"
.LP
You can set the following variables in your environment:
.LP
INSTALL_RC [default: $HOME/.Installrc]
.IP
file containing default options for \fBInstall\fR
.LP
INSTALL_STATE [default: $HOME/.Install.state]
.IP
where \fBInstall\fR keeps its state information
.LP
INSTALL_DIR [default: /tmp/Install.username]
.IP
where \fBInstall\fR does its work.  This can be overridden on
the command line with \fB\-d\fR.
.LP
INSTALL_LIB [default: $HOME/LibInstall]
.IP
where \fBInstall\fR gets/puts library files.  This can be overridden on
the command line with \fB\-D\fR.
.LP
INSTALL_CP [default: cp -p]
.IP
the command to copy files locally
.LP
INSTALL_RCP [default: rcp -p]
.IP
the command to copy files remotely
.SH "EXAMPLES"
.LP
.B
Install -w /ws/blort -t machine:/
.IP
.RI "installs the system built in workspace " /ws/blort " on " machine:/
.LP
.B
Install -w /ws/blort -T machine:/tmp
.br
.B
rsh machine -l root "cd /; tar xvf /tmp/Install.tar"
.IP
is an equivalent way to do the previous example
.LP
.B Install
.IP
makes a tarfile containing a sun4c kernel,
and places it in /tmp/Install.username/Install.sun4c.tar.  However, if you
are in one of the arch directories (e.g. $SRC/uts/sun4m) when you invoke
.BR Install ,
you will get a tarfile for that architecture instead.
.LP
.B
Install -k sun4m -w /ws/on493 -t mpbox:/ ufs
.IP
installs a new sun4m ufs module from workspace /ws/on493 on mpbox:/
.SH "FILES"
$HOME/.Installrc, $HOME/.Install.state
.SH "SEE ALSO"
.BR tar "(1), " rsh "(1), " rcp "(1)"
.SH "BUGS"
.BR tar "(1) and " rsh "(1)"
do not have particularly useful exit codes.  To compensate,
.B Install
feeds stderr through grep -v and throws away error messages which it
considers harmless.  If there's anything left,
.B Install
assumes it is fatal.  It's a hack, but it works.
